STEAM-BOILER.

SPECIFICATION formingpart of Letters Patent N 0. 714,084, dated November 18, 1902.

Application filed April 5, 1902. Serial No. 101,485. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM ARMSTRONG WOODESON, a subject of the King of Great Britain and Ireland, residing at Gatesheadon-Tyne, in the county of Durham, England,

have invented Improvements in Steam-Boilers, of which the following is a specification.

This invention has reference to water-t ube steam-boilers, and according thereto the fur- 1o nace is provided with an upwardly-extending combustion-chamber surrounded by an outer casing, the space between being divided by partitions into a number of compartments in each of which is a steam-generating element comprising water-tubes whose ends are fixed in tube-plates, a water-chamber below the lower tube-plate and a water-space above the upper tube-plate, the arrangement being such that the products of combustion are compelled to take a long course before leaving the heating-surface of the boiler, so that a large proportion of their heat will be transmitted to the water before they finally pass into the uptake or chimney.

Referring to the accompanying drawings, Figure l is a front elevation of one arrangement of boiler according to this invention. Fig. 2 is a vertical section on the lineA A, Fig. 1. Fig. 3 is a plan, and Fig. 4 a hori- 0 zontal section, on the line B B. Fig. 5 is a diagram illustrating a development of the series of element-containing compartments,and Figs. 6 and '7 are detail views at right angles to each other of'one of the tube-plates of an element.

a is the furnace, which may be dollblw arranged in two separate parts and built of brickwork cased in iron, as shown, and b is a large cylindrical combustion-chamber, which 40 communicates with the rear end of each part of the furnace a and may be built of or lined with refractory material.

0 is the outer casing, which in this example concentrically surrounds the combustionchamber, and d designates radial partitions, which divide the annular space between into a series of compartments e, f, g, h, t', andj.

It 70 are the water-tubes, those of each element being fixed at the ends in an upper tubeplate Z and a lower tube-plate 'm.

are suitably shaped for the purpose. l

To each tubeplate m an inverted-domeshaped cover 19 is bolted, so as to form a lower water-space q, and on each tube-platel is riveted or bolted a flanged annular wall 1', which forms an upper Water-space s. The water-spaces s of the elements that are contained in the compartment 6 and h are riveted to a horizontal steam or steam-and-water drum 75, while the water-space s of each of 7cthe elements in the remaining four compartments is closed in by dome-shaped covers u, bolted to the annular wall 1', and pipes 12 and to connect said spaces to the under side of the drumt to about the level of the center line thereof, the said pipes v and w forming, respectively, down-comers and up-comers. These pipes o and to may either be bolted or riveted to the walls 1" of the water-spaces, or the Lip-comers may be led from their waterspaces into or near the bottom of the steamand-water'drum and be fitted with vertical pipes to discharge the contents above waterline.

The compartments 6, f, and j, which are at the front of the boiler, are shorter than the remaining compartments, so as to enable the furnace to be arranged as far as may be underneath the boiler.

In the top of the drum t and immediately above the water-tubes 70in the elements whose water-spaces 8 directly communicate therecommunicate, respectively,with the top of the combustion-chamber and the bottom of the uptake or chimney y, is formed with an op ening 2, the said openings being disposed alternately at top and bottom, so as to cause the gases after leaving the combustion-chamber to take a zigzag course up and down through the several compartments, around and through the water-tubes of the elements, escaping from the last compartment j to the uptake or chimney y. With such a construction of boiler it will be seen that the gases have an opportunity of being more completely consumed than is usual, and the products of combustion travel in contact with such a length of heating-surface that a large proportion of their heat is transmitted to the water.

The outer wall of each of the compartments efg h may be in the form of or provided with doors 1 1, which may be of wrought or cast iron and are hinged to flanges 2 on the partitions d, as shown in Fig. 1, and secured at top and bottom to channel-bars 3, extending'around the row of compartments. The doors 1 1 are covered on the inside with refractory material.

By means of the manholes 01:, covers p and u, and doors 1 1 the various parts of the boiler are rendered accessible for cleaning, repairing, &c. ,7 I

A baffie or damper (not shown) may be arranged to control the orifice 5 in the wall of the combustion -chamber and leading into the first compartment e, so as to regulate the flow and supply of gases from the furnaces to the compartments, this baffle or damper being actuated from the outside.

The short front elements in the compartments e, f, andjare sludged at one operation through a common sludge-pipe b, to which branches 7 connect the bottoms of the covers u, and the longer elements in the rear compartments g, h, and v through a pipe 8, that is common to them.

The baffles or partitions (1 (shown in the drawings) are castings lined with refractory material and bolted at top and bottom to the flanges of the tube-plates; but they may consist of walls built up of ordinary fire-bricks or quarles and resting on the bottom tube-plates. Where orifices are required at top, the necessary space'is left, and where orifices are required at the bottom arches are built to form these orifices and the wall continued up to the top tube-plate. In such cases the tube-plates can be bolted direct to each other or distancepieces can be fitted between the tube-plate flanges before they are bolted together.

Means are in some cases provided for ad mitting hot air to the compartments either at the top or the bottom, or both, so as to insure proper combustion.

The feed -water may be admitted to the steam-and-water drum or into the bottom water-space of one of the elements, as may be desired.

As will be understood, the arrangement may be modified to suit particular requirements, and in some cases special external down-comer pipes may be provided, the several elements then being connected to the steam-and-water drum or vessel only above its lowest part; also, in some cases the gases on leaving the last compartment can be led into a brick or other flue contained within and running lengthwise of the upwardly-extending combustion-chamber and thence to a main flue underground.
